Hi, I am having a troubling error from my x310 USRP whenever I try to
pull samples using the USRP source block. The error message I am
getting is:
[ERROR] [STREAMER] The receive packet handler caught a value exception.
ValueError: Bad CHDR or packet fragment
WARN: USRP Source Block caught rx error code: 15
[ERROR] [RX FLOW CTRL] Error unpacking packet: ValueError: Bad CHDR or
packet fragment
The most basic flowgraph that creates this error is a USRP Source
connected directly to a QT Time plot. It also happens when I try to
run: 1) uhd_cal_rx_iq_balance, 2) uhd_fft, 3) uhd_cal_tx_dc_offset,
My gnuradio version is 3.7.13.4, UHD version is UHD
3.14.0.0-88-g6013a511, and i have just reinstalled both to make sure
it is not a software issue. I am able to successfully run
uhd_find_devices and uhd_usrp_probe. I am also able to run a USRP sink
block without error, if that helps identify the problem.
Anyone have a fix for this?
Andrew
What type of Ethernet interface do you have on your system?
Is this a VM, or a on-the-hardware system?
Is this on Windows or Linux?
